GN Netcom's Avaya EHS-1 Adapter enables remote Electronic Hook-switch Control (EHS) with GN/Jabra wireless headsets (ie. GN 9350 or GN 9120), and the Avaya model phones listed below. This means that users can answer and end calls up to 300 ft. away from their desks without the use of a Handset Lifter (GN1000). Please see if your phone model is compatible before ordering this product.
